drm/amd/display: Only skip update for DCFCLK, UCLK, FCLK on overclock

[Description]
- Update clocks is skipped in the GPU overclock sequence
- However, we still need to update DISPCLK, DPPCLK, and DTBCLK
  because the GPU overclock sequence could temporarily disable
  ODM 2:1 combine because we disable all planes in the sequence
